Thus Gentiles who lack the revelation of scripture are said to have the law 'written on their hearts' ( Romans 2:15) so that they can egitimatelybe held accountable when they violate what they are capable of seeing is right." Wilkins says that in this view, the primary moral laws are universally known, are discernible through reason, are innate in all people (and, therefore, binding on all), and their practice contributes to individual and community well-being. Elements of each of these theories can be found in the Bible and the early church. By the twenty-first century, additional traditions had formed in Christian ethics based on different interpretations of divine attributes, how God communicates moral knowledge, differing anthropological conclusions, and different ideas about how the believer should relate to the Christian community and the outside world. One aspect of these differences, which focuses on the church and its mission, developed into what Wilkins calls ''prophetic ethics''. Its starting point is social justice and

is an early incorporation of the prophetic model reaching back to the Radical Reformation. They differed from other Reformation groups in that they saw the church as a unique type of human organization and its problems, not as theological, but as ethical failures rooted in entanglement with politics. Anabaptism began among the dispossessed and persecuted with isolationist tendencies, whereas modern versions, such as the Social Gospel movement, have turned toward cultural engagement. Post-colonial thought, and black, feminist and liberation theologies are examples of this Christian ethic engaging the "sinfulness of the social order".

Christian ethics began its development during the early Christian period, which is generally defined as having begun with the ministry of Jesus (–30) and ended with the
First Council of Nicaea The First Council of Nicaea ( ; ) was a council of Christian bishops convened in the Bithynian city of Nicaea (now İznik, Turkey) by the Roman Emperor Constantine I. The Council of Nicaea met from May until the end of July 325. This ec ...

, which prompted Christians to think through aspects of Roman society in Christian terms. Christian ethics sought "moral instruction on specific problems and practices" which were not sophisticated ethical analyses, but simple applications of the teachings (and example) of Jesus about issues such as the role of women, sexuality and slavery. After Christianity became legal in the 4th-century Roman Empire, the range and sophistication of Christian ethics expanded. Through figures such as

Modern Christian ethics

After separating from theology, the primary concern of nineteenth century Christian ethicists was the study of human nature. "Beginning with the rise of Christian social theory" in the nineteenth century, theologian John Carman says Christian ethics became heavily oriented toward discussion of nature and society, wealth, work, and human equality. Carman adds that, in the nineteenth and twentieth centuries, "the appeal to inner experience, the renewed interest in human nature, and the influence of social conditions upon ethical reflection introduced new directions to Christian ethics". Carman adds that the question of how the Christian and the church relates to the surrounding world "has led to the development of three distinct types of modern Christian ethics: "the church, sect and mystical types". In the church type (i.e., Roman Catholicism and mainstream Protestantism), the Christian ethic is lived within the world, through marriage, family, and work, while living within and participating in their respective towns, cities and nations. This ethic is meant to permeate every area of life. The ethic of the

It is practiced by withdrawing from the non-Christian world, minimizing interaction with that world, while living outside or ''above'' the world in communities separated from other municipalities.

, the "kingdom ideals" of Jesus, recognize the community-based dimension of sin, and are critical of the traditional theories of Christian ethics. In the early twenty-first century, Professor of philosophy and religion at Maryville, William J. Meyer, asserts that Christian ethicists often find themselves on one side of a discussion of ethics, while those advocating a secular worldview that denies God and anything transcendent are their opponents on the other side. He says these discussions are divided by beliefs about how claims ought to be addressed, since both sides assume there is a polarity between human reason and the authority of scripture and tradition. Meyer asserts that the answer to this difficulty lies in modern Christian ethics embracing secular standards of rationality and coherence, while continuing to refuse the secular worldview and its premises and conclusions. Meyer describes this effort to affirm religion "within the context of modern secularity" as "the critical fault line in the contemporary world".


Philosophical core

Gustafson sets out four basic points he asserts that any theologically grounded ethic must address: * metaphysics: all other concepts and beliefs rest on metaphysics; it is about how being and existence are defined through God, His will and His relation to humans; * epistemology: how humans know, and distinguish, justified belief from mere opinion, through human experience, community, nature and man's place in it; * ethics: the system and principles used by persons as moral agents; * applications: how persons make moral choices, judge their own acts, the acts of others, and the state of the world.


Metaphysical foundations

The Christian metaphysic is rooted in the biblical metaphysic of God as "Maker of Heaven and earth". Philosopher Mark Smith explains that, in the Bible, a fundamental ontology is embodied in language about power, where the world and its beings derive their reality (their being, their power to exist, and to act) from the power of God (Being itself). Theology and philosophy professor Jaco Gericke says that metaphysics is found anywhere the Bible has something to say about "the nature of existence". According to Rolf Knierim, the Bible's metaphysic is "dynamistic ontology" which says reality is an ongoing dynamic process. In this view, God "gives the universe its basic order", and its "formal statistical patterns", generally referred to as ''natural laws,'' but also allows them to develop organically with minimum interference. According to Roger E. Olson, the Christian view of the nature of reality can also be called "biblical theism" or "biblical personalism": the belief that "ultimate reality is a personal God who acts, shows and speaks..." Mark Smith explains that, in metaphysical language, the power of lesser beings participates in Power itself, which is identified as God. Humanity is the highest level of development in creation, but humans are still creatures. This view asserts that humans reflect the relational nature of God. In the Christian metaphysic, humans have free will, but it is a relative and restricted freedom. Beach says that Christian ''voluntarism'' points to the ''will'' as the core of the self, and that within human nature, "the core of who we are is defined by what we love", and this determines the direction of moral action. Humans reflect the nature of ultimate reality, therefore they are seen as having a basic dignity and value and should be treated, as

said, as "an end in themselves" and not as a means to an end. Humans have a capacity for reason and free will which enable making rational choices. They have the natural capacity to distinguish right and wrong which is often called a conscience or natural law. When guided by reason, conscience and grace, humans develop virtues and laws. In Christian metaphysics according to Beach, "''Eternal Law'' is the transcendent blueprint of the whole order of the universe... ''Natural Law'' is the enactment of God's eternal law in the created world and discerned by human reason."


Paul

Some older scholarship saw Paul's moral instruction as separate from his theology, saying his ethic was adopted from Hellenist philosophy. Modern scholarship has broken up these old paradigms. "Christianity began its existence as one among several competing Jewish sects or movements. Judaism was not one thing, either in Judea and Galilee or in the Diaspora, nor were the boundaries among the varieties of Judaism fixed or impermeable". Paul's writings reflect this mix. He called himself a "Hebrew of Hebrews" but he did so in fluent Greek. He avoided the high Atticistic Greek style of rhetoric but invented his own by making use of the strategies of the Greco-Roman orators. He employed Jewish strategies for interpretation and used the Jewish traditions for reading the apocalyptic scriptures including the sectarian and what would later be the rabbinic ones. But he was also aware of the Greco-Roman philosophical discussions of his day. He mixed things that modern scholars have seen as unmixable, changing and transforming key elements within the Jewish/Hellenist paradigm into something uniquely Christian. Paul's theological and apocalyptic views form the foundation of his ethical views, and the foundation of Paul's theology is the cross of Christ. When the Corinthian church begins in-fighting, Paul responds by saying they have abandoned their core teachings: the cross and the centrality of God. These were the themes that formed the foundation of all of Paul's preaching. The cross informs Paul's ethic theologically, eschatological, and Christologically, reconciling people to God but also summoning them to service. "Paul has more to say about human nature nd ethical behaviorthan any other early Christian author", and Paul holds up the cross as motivation for ethical conduct. Practicing the cross by living with the self, crucified, is associated in 1 Corinthians and Ephesians with Christian unity, self-sacrifice, and the Christian's future hope. "The cross is increasingly recognized as providing a general foundation for Christian ethics".


Epistemology

Christian ethics asserts that it is possible for humans to know and recognize truth and moral good through the application of both reason and revelation. Observation, reasoned deduction and personal experiences, which includes grace, are the means of that knowledge. Rabbinic scholar Michael Fishbane goes on to add that human knowledge of God is understood through language, and "It is arguably one of Judaism's greatest contributions to the history of religions to assert that the divine Reality is communicated to mankind through words."

's (1509–1564) teaching that persons are created with a sense of God (sensus divinitatis). Even when this sense is not apparent to the person because of sin, it can still prompt them to believe and live a life of faith. This means belief in God may be seen as a properly ''basic'' belief similar to other basic human beliefs such as the belief that other persons exist, and the world exists, just as we believe we exist ourselves. Such a basic belief is what Plantinga calls a "warranted" belief even in the absence of evidence. Paul Moser argues for volitional epistemology. He systematically contends that, if the God of Christianity exists, this God would not be evident to persons who are simply curious, but would instead, only become evident in a process involving moral and spiritual transformation. "This process might involve persons accepting Jesus Christ as a redeemer who calls persons to a radical life of loving compassion, even the loving of our enemies. By willfully subjecting oneself to the commanding love of God, a person in this filial relationship with God, through Christ, may experience a change of character (from self-centeredness to serving others) in which the person's character (or very being) may come to serve as evidence of the truths of faith." According to Gustafson, Christian epistemology is built on different assumptions than those of philosophical epistemology. He says the Christian ethic assumes either a condition of piety, or at least a longing for piety. He defines piety as an attitude of respect evoked by "human experiences of dependence upon powers we do not create and cannot fully master". Gustafson adds that such piety must be open to a wide variety of human experiences, including "data and theories about the powers that order life..." He says this Christian knowing engages the affections, and takes the form of a sense of gratitude. Gustafson sees trust as an aspect of such knowing: underneath science is a trust that there is an identifiable order and discoverable principles beneath the disarray of complex data; this is comparable to the trust of the Christian faith that "there is unity, order, form and meaning in the cosmos ...of divine making". Gustafson adds that: "Knowledge conditions are relative to particular communities" and all human knowledge is based on the experiences we have in the cultures within which we live.


Basic ethical principles

Christian ethics asserts the ontological nature of moral norms from God, but it is also accountable to standards of rationality and coherence; it must make its way through both what is ideal and what is possible. Thus, Beach asserts that some principles are seen as "more authoritative than others. The spirit, not the letter, of biblical laws becomes normative." The diversity of the

from its beginnings, but Wogaman points out that Christian ethicists have not always agreed upon "the meaning of revelation, the nature of reason, and the proper way to employ the two together". He says there are at least seven ethical principles that Christian ethicists have perennially reinterpreted.


Good and evil

Since the Christian ethic begins with God as the source of all, and since God is defined as the ultimate good, the presence of evil and suffering in the world creates questions often referred to as the
problem of evil The problem of evil is the philosophical question of how to reconcile the existence of evil and suffering with an Omnipotence, omnipotent, Omnibenevolence, omnibenevolent, and Omniscience, omniscient God.The Stanford Encyclopedia of Philosophy, ...

summarizes: "Is God willing to prevent evil, but not able? Then he is not omnipotent. Is he able, but not willing? Then he is malevolent. Is he both able and willing? Then from whence comes evil?" Addressing this requires a theological and philosophical response which

thinks is the Christian ethic's greatest challenge. Todd Calder says there are at least two concepts of evil applicable to this question: a broad concept and a narrow one. A broad concept of evil defines it as any and all pain and suffering, but this quickly becomes problematic. Evil cannot be correctly understood on a simple scale of pleasure vs. pain, since the National Institute of medicine says pain is essential for survival. Marcus Singer says that a workable definition of evil requires that: "If something is really evil, it can't be necessary, and if it is really necessary, it can't be evil." The Christian story "is a story of the salvific value of suffering", therefore the Christian ethic, while assuming the reality of evil and recognizing the power of suffering, does not support the view that all suffering is evil. The narrow definition of evil is used instead. It is defined as the attempt or desire to inflict significant harm on a victim, without moral justification, perpetrated only by moral agents capable of independent choices. The Christian ethic offers three main responses to the problem of evil and a good God. The freewill defense by

have also produced process theodicies which assert God's power and ability to influence events are, of necessity, limited by human creatures with wills of their own. Nicola Hoggard Creegan says natural evil exists in the form of animal suffering, and she offers a theodicy in response that is based on the parable of the wheat and the tares (). She argues that nature can be understood as an intertwined mix of the perfect and the corrupted, that God could not have made one without allowing the existence of the other, and that this is because of the natural laws involved in creation. Christian ethicists such as Christopher Southgate have also produced evolutionary theodicies which use evolution to show that the suffering of biological creatures, and belief in a loving and almighty God, are logically compatible. Generally, Christians ethicists do not claim to know the answer to the "Why?" of evil. Plantinga stresses that this is why he does not proffer a theodicy but only a defense of the logic of theistic belief. The approach of Christian ethics to pain and evil is summarized by Sarah Pinnock who asserts that: "Direct contact with God does not answer Job's questions, but it makes meaning, and the acceptance of suffering, possible."


Inclusivity, exclusivity and pluralism

There is an inherent tension between inclusivity and exclusivity in all the Abrahamic traditions. According to the book of Genesis, Abraham is the recipient of the promise of God to become a great nation. The promise is given to him and his "seed", exclusively, yet the promise also includes that he will become a blessing to all nations, inclusively ( Genesis 12:3). The God of the Bible is the inclusive God of all nations and all people ( Galatians 3:28), and the Great Commission ( Matthew 28:19) is a command to go to all nations, yet Wogaman points out that Christians are referred to in the New Testament as the "elect" ( Romans 8:33 Matthew 24:22) implying God has chosen some and not others for salvation. Christians and non-Christians have, throughout much of history, faced significant moral and legal questions concerning this ethical tension. During the Reformation, Christians pioneered the concept of
religious freedom Freedom of religion or religious liberty, also known as freedom of religion or belief (FoRB), is a principle that supports the freedom of an individual or community, in public or private, to manifest religion or belief in teaching, practice ...
which rests upon an acceptance of the necessity and value of pluralism, a modern-day concept often referred to as moral ecology.


Law, grace and human rights

Christian ethics emphasizes morality. The law and the commandments are set within the context of devotion to God but are deontological standards defining what this morality is. The prophets of the Old Testament show God as rejecting all unrighteousness and injustice and commending those who live moral lives. In tension with this, there is also "a deep expression of God's love for undeserving sinners". Wogaman says the apostle Paul refers to this as grace: "being treated as innocent when one is guilty". Wogaman argues that: "Part of the biblical legacy of Christian ethics is the necessity somehow to do justice to both" law and grace. Author Stanley Rudman asserts that
human rights Human rights are universally recognized Morality, moral principles or Social norm, norms that establish standards of human behavior and are often protected by both Municipal law, national and international laws. These rights are considered ...
(as defined post–WWII) is the language through which the Christian ethic is able to relate these concepts to the world. In a convergence of opinion among Catholics, Lutherans, Reformed, and others, this has led to a support of human rights becoming common to all varieties of Christian ethics.


Authority, force and personal conscience

Wogaman asserts that "love is, and must remain", the foundation of the Christian ethical system. In the Sermon on the Mount, Jesus summarizes his ethical teachings to those who would follow a new path that diverged from established law: " turn the other cheek" Matthew 5:38–39, "love your enemies" Matthew 5:43–45, "bless those who persecute you" Romans 12:14–21. Jesus' followers must not murder, as the law says, but they must also not hold the kind of hatred that leads to it, but must forgive instead. Wogaman adds that, "justice, as the institutional structure of love, is inevitably dependent upon other incentives including, ultimately, the use of force". Both the Old and the New Testaments give explicit commands to respect the state's authority to "carry the sword" ( Romans 13:4). Christian ethics is, and has been repeatedly, divided over this interaction between obedience to authority and authority's power to enforce that obedience in contrast with one's personal responsibility to love and forgive.


Self-affirmation and self-denial

According to the book of Genesis, God created and declared creation, including humans, good ( Genesis 1:31). The
Song of Songs The Song of Songs (), also called the Canticle of Canticles or the Song of Solomon, is a Biblical poetry, biblical poem, one of the five ("scrolls") in the ('writings'), the last section of the Tanakh. Unlike other books in the Hebrew Bible, i ...
depicts sensual love as good. Other parts of the Old Testament depict material prosperity as a reward. Yet, the New Testament references the life of the Spirit as the ultimate goal, and warns against worldliness. In the traditional view, this requires self-sacrifice, self-denial and self-discipline, and greatness lies in being a servant to all ( Mark 10:42–45). Yet according to ethicist Darlene Weaver, "there is no ontological split between self/other; there is no monolithic polarity of self-interested action versus other-regardingness". Christian ethics has not traditionally contained concepts of self-love as a good. However, Koji Yoshino asserts that, within the Christian ethic, "altruistic love and self-love are not contradictory to each other. Those who do not love themselves cannot love others, nevertheless, those who ignore others cannot love themselves."


Wealth and poverty

There are a variety of Christian views on poverty and wealth. At one end of the spectrum is a view which casts wealth and materialism as an evil to be avoided and even combatted. At the other end is a view which casts prosperity and well-being as a blessing from God. The Christian ethic is not an opponent of poverty since Jesus embraced it, but it is an opponent of the destitution that results from social injustice. Kevin Hargaden says "No Christian ethic can offer a consistent defense of massive wealth inequality." Some Christians argue that a proper understanding of Christian teachings on wealth and poverty requires a larger view where the accumulation of wealth is not the central focus of one's life but rather a resource to foster the "good life". Professor David W. Miller has constructed a three-part rubric which presents three prevalent attitudes among Protestants towards wealth: that wealth is (1) an offense to the Christian faith (2) an obstacle to faith and (3) the outcome of faith.


Gender and sexuality

Classicist Kyle Harper writes that sexuality was at the heart of Christianity's early clash with its surrounding culture. Rome's concept of sexual morality was centered on social status, whereas the Christian ethic was a "radical notion of individual freedom centered around a libertarian paradigm of complete sexual agency". This meant the ethical obligation for sexual self-control was placed on the individual, male and female, slave and free, equally, in all communities, regardless of status. In Paul's letters, ''porneia'' was a single name for the array of sexual behaviors outside marital intercourse that became a central defining concept of sexual morality, and shunning it, a key sign of choosing to follow Jesus. For Paul, "the body was a consecrated space, a point of mediation between the individual and the divine". Views on sexuality in the early church were diverse and fiercely debated within its various communities, and this continues. Throughout the majority of

Politics

. Where pacifism and non-resistance can be seen as ideals in action, evangelical theologian Harold O. J. Brown describes just wars, preventive wars and crusades as "actions in support of an ideal". In all four views, the Christian ethic presumes war is immoral and must not be waged or supported by Christians until certain conditions have been met that enable the setting aside of that presumption. Pacifism and non-resistance are opposed to all forms of physical violence based on belief that the example of Christ demonstrates it is better to suffer personally than to do harm to others. Non-resistance allows for non-combatant service where pacifism does not. They both presuppose the supersession of the New Testament over the Old, and believe in the separation of church and state to the degree the Christian does not owe obedience and loyalty to the state if that loyalty violates personal conscience. Both pacifism and non-resistance are interpreted as applying to individual believers, not corporate bodies, or "unregenerate worldly governments". Mennonite minister Myron Augsburger says pacifism and non-resistance act as a conscience to society and as an active force for reconciliation and peace. Preventive war, also sometimes referred to as crusade, and just war recognize that harm can result from failing to resist a tyrannical enemy. Preventive war is waged in anticipation of an act of aggression that would violate ideals of human rights, decency, and a sense of right and wrong. Counter-terrorism is a kind of preventive war. Preventive war/crusade can also be seen as an attempt to set right a past act of aggression that was not responded to at the time it occurred. It is not necessarily religious in nature or focus, but "attempts to undo what no one had the right to do in the first place": the First Crusade of the Middle Ages, the First Gulf War, and World War II. Supporters of Just War theory say war can only be justified as self-defense or the defense of others. The biblical provisos for these types of war are not supersessionist, and therefore are more from the Old Testament than the New. The last 200 years have seen a shift toward just war in the moral focus concerning the state's use of force. Justification for war in the twenty-first century has become the ethic of intervention based on humanitarian goals of protecting the innocent.


Criminal justice

Early criminal justice began with the idea that God is the ultimate source of justice, and is the judge of all, including those administering justice on earth. Within Christian ethics, this view places the greatest responsibility for justice on judges with moral character, who are admonished not to lie or be deceptive, not to practice racial prejudice or discrimination, or to let egoism lead them to abuse their authority, as central to the administration of justice. Biblical ethicist Christopher Marshall says there are features of covenant law from the Old Testament that have been adopted and adapted to contemporary human rights law, such as due process, fairness in criminal procedures, and equity in the application of law. How justice is defined has varied. Aristotle's classic definition of justice, ''giving each their due'', entered into Christian ethics through scholasticism and Thomas Aquinas in the Middle Ages. For Aristotle and Aquinas that meant a hierarchical society with each receiving what was due according to their social status. This allows for the criminal justice system to be retributive, to discriminate based on social standing, and fails to recognize a concept of universal human rights and responsibilities. Philip Wogaman says that after Aquinas, the Radical Reformation, the
social gospel The Social Gospel is a social movement within Protestantism that aims to apply Christian ethics to social problems, especially issues of social justice such as economic inequality, poverty, alcoholism, crime, racial tensions, slums, unclean en ...
and liberation theology redefined getting one's due into what became the Marxist formula: "from each according to his ability, to each according to his need". Along these lines, justice had an egalitarian form while retaining male domination, and defining justice for slaves as paternalistic care. Wogaman says that these issues will "continue to occupy Christian ethics for years to come".


Capital punishment

In Christian ethics of the twenty-first century, capital punishment has become controversial, and there are Christian ethicists on both sides. Biblical ethicist Christopher Marshall says there are about 20 offenses that carry the death penalty in the Old Testament. He adds that "contemporary standards tend to view these laws of capital punishment as cavalier toward human life", however, the ancient ethic of "covenantal community" suggests the value of life was as much communal as individual. In contemporary society, capital punishment can be seen as respect for the worth of the victim by calling for the equal cost to the offender; it can also be seen as respect for the offender, treating them as free agents responsible for their own choices who must bear the responsibility for their acts just as any citizen must. According to Jeffrey Reiman, the argument against capital punishment is not based on the offender's guilt or innocence, but on the belief that killing is wrong, and is therefore never a permissible act, even for the state. G. C. Hanks argues against the death penalty by saying it "is not effective in fighting crime, costs more than life sentences, reinforces poverty and racism, and causes innocent persons to be executed". He argues that it interferes with creating a just and humane society, negatively impacts the families of victims, and race issues, and can be seen as "cruel and unusual punishment". These arguments leave retribution as the primary supporting argument in favor of capital punishment, and Professor Michael L. Radelet says retribution's moral base is a problem for a Christian ethic. The
Catholic Church The Catholic Church (), also known as the Roman Catholic Church, is the List of Christian denominations by number of members, largest Christian church, with 1.27 to 1.41 billion baptized Catholics Catholic Church by country, worldwid ...
has historically taught that capital punishment is permissible, but during the twentieth century, popes began to argue that it could not be justified under present-day circumstances as there were other ways to protect society from offenders. Capital punishment has been abolished in many countries, and Radelet predicts that increasing opposition from religious leaders will lead to its abolition in America as well.


Relationships

In most ancient religions the primary focus is on humankind's relationship to nature, whereas in the Christian ethic, the primary focus is on relationship with God as the "absolute moral personality". This is demonstrated as a focus on relationship itself as a primary concern in all Christian ethics.


Neighbors

calls an "enlightened unselfishness". When the Pharisee asked Jesus: "Who is my neighbor?" (Luke 10:29), Grenz says the questioner intended to limit the circle of those to whom this obligation was due, but Jesus responded by reversing the direction of the question into "To whom can I be a neighbor?". In the parable of the "Good Samaritan", the use of a racially despised and religiously rejected individual as an example of the good, defines a neighbor as anyone who responds to those in need.

Before the twelfth and thirteenth centuries, ordination was dedication to a particular role or ministry, and in this capacity, women in the church were ordained up until the 1200s. When theologians of this medieval period circumscribed the seven sacraments, they changed the vocabulary and gave the sacraments exclusively to male priests. In the nineteenth century, ''rights for women'' brought a wide variety of responses from Christian ethics with the Bible featuring prominently on both sides ranging from traditional to feminist. In the late twentieth century, the ordination of women became a controversial issue. Linda Woodhead states that, "Of the many threats that Christianity has to face in modern times, gender equality is one of the most serious."

concurred but added an exception for abandonment by an unbelieving spouse. Augustine wrote his treatise on divorce and marriage, ''De adulterinis coniuigiis'', in which he asserts couples may only divorce on the ground of ''fornication'' (adultery) in 419/21, even though marriage did not become one of the seven sacraments of the church until the thirteenth century.

Sexuality and celibacy

Lisa Sowle Cahill refers to sex and gender as most difficult topics in new studies of Christian ethics. As "the rigidity and stringency of ...traditional moral representation has collided head-on with historicized or 'postmodern' interpretations of moral systems", Cowell says tradition has acquired new forms of patriarchy, sexism, homophobia and hypocrisy. Feminist critics have suggested that part of what drives traditional sexual morality is the social control of women, yet within postmodern western societies the "attempt to reclaim moral autonomy through sexual freedom" has produced a loss of all sense of sexual boundaries. Cahill concludes that, in contemporary Western culture, "Personal autonomy and mutual consent are almost the only criteria now commonly accepted in governing our sexual behavior." The gospel requires that all relationships be reconfigured by new life within the community, yet the New Testament has no systematic investigation into all facets of any moral topic, no definitive guidance for the many variations of moral problems that exist in the twenty-first century. According to Lisa Sowle Cahill, "Traditional societies place sex and gender in the context of community, family and parenthood; modern societies respect reciprocity, intimacy and gender equality." Cowell says, New Testament authors challenge that which perpetuates sin, and encourage the transformation that "embodies the reign of God". While Jesus made reference to ''some that have made themselves eunuchs for the kingdom of heaven,'' there is no commandment in the New Testament that priests must be unmarried and celibate. During the first three or four centuries, no law was promulgated prohibiting clerical marriage. Celibacy was a matter of choice for bishops, priests, and deacons. In the twenty-first century, the Roman Catholic Church teachings on celibacy uphold it for monastics and some priests. Protestantism has rejected the requirement of celibacy for pastors, and they see it primarily as a temporary abstinence until the joys of a future marriage. Some modern day evangelicals desire a more positive understanding of celibacy that is more like Paul's: focused on devotion to God rather than a future marriage or a lifelong vow to the Church.


Slavery and race

In the twenty-first century, Christian organizations reject slavery, but historically Christian views have varied, embracing both support and opposition. Slavery was harsh and inflexible in the first century when Christian ethics began, and slaves were vulnerable to abuse, yet neither Jesus nor Paul ordered the abolition of slavery. At this time, the Christian view was that morals were a matter of obedience to the ordained hierarchy of God and men. Paul was opposed to the political and social order of the age in which he lived, but his letters offer no plan for reform beyond working toward the apocalyptic return of Christ. He did indirectly articulate a social ideal through the Pauline virtues, the "faith, hope and love" of his

, by designating love as the highest of all virtues; and he indirectly undermined the mistreatment of women, children and slaves through his teachings on marriage and through his own personal lifestyle. Stanley K. Stowers, professor of religious studies, asserts the view that Paul's refusal to marry and set up a household that would require slaves, and his insistence on being self-supporting, was a model followed by many after him that "structurally attacked slavery by attacking its social basis, the household, and its continuity through inheritance from master to master". In the early 4th century,

in the West. Economics drove its development, but historian Herbert S. Klein adds that the trade was abolished in the U.S., Britain and Europe while it was still profitable and important to those respective economies. Early abolitionist literature viewed the abolition of slavery as a moral crusade. Churches became vital parts of that effort with abolitionists, reformers, and supporters of slavery all using Christian ethics to justify their relative positions. Racial violence over the last decades of the twentieth century and the early decades of the twenty first demonstrate how troubled issues involving race remain. Paul Harvey says that, in the 1960s, "The religious power of the civil rights movement transformed the American conception of race." The social power of the religious Right responded in the 70s by recapturing and recasting many evangelical concepts into political terms including support of racial separation. Since then, Harvey says the

). The prosperity gospel's multi-cultural demographic may suggest much about the future of Christian ethics and race.


Bioethics

Bioethics is the study of the life and health issues raised by modern technology that attempts to discover what medical ethicist Scott B. Rae and Christian ethicist Paul M. Cox call "normative guidelines built on sound moral foundations". This is necessary because the moral questions surrounding new medical technologies have become complex, important and difficult. David VanDrunen, professor of systematic theology and Christian ethics, opines that with the tremendous benefits of medical advances, have come the "eerie forebodings of a future that is less humane, not more". In what Rae and Cox describe as "a best selling exposé", Jeff Lyon in ''Playing God in the Nursery'' charged physicians with "prematurely withdrawing life-sustaining technology from seriously ill newborns". Remedies for infertility enable researchers to create embryos as a disposable resource for stem cells. Scripture offers no direct instruction for when a right to life becomes a right to death. The Catholic bio–ethic can be seen as one that rests on natural law. Moral decision making affirms the basic "goods" or values of life, which is built on the concept of a hierarchy of values, with some values more basic than others. For example, Catholic ethics supports self-determination but with limits from other values, say, if a patient chose a course of action that would no longer be in their best interests, then outside intervention would be morally acceptable. If there is conflict over how to apply conflicting values, Rae and Cox say that then a ''proportionate reasoned decision'' would be made. This is defined as including values such as preservation of life, human freedom, and lessening pain and suffering while also recognizing that not all values can be realized in these situations. The Protestant Christian ethic is rooted in the belief that ''
agape (; ) is "the highest form of love, charity" and "the love of God for uman beingsand of uman beingsfor God". This is in contrast to , brotherly love, or , self-love, as it embraces a profound sacrificial love that transcends and persists rega ...
'' love is its central value, and that this love is expressed in the pursuit of good for other persons. This ethic as a social policy may use natural law and other sources of knowledge, but in the Protestant Christian ethic, ''apape'' love must remain the controlling virtue that guides principles and practices. This approach determines the moral choice by what is the most love-embodying action within a situation. Rae and Cox conclude that, in this view, actions that can be seen as wrong, when they are acts of maximal love toward another, become right.


Genetic engineering

New technologies of prenatal testing, DNA therapy and other genetic engineering help many, yet Wogaman asserts they also offer ways in which "science and technology can become instruments of human oppression". Manipulating the genetic code can prevent inheritable diseases and also produce, for those rich enough, designer babies "destined to be taller, faster and smarter than their classmates". Genetic technologies can correct genetic defects, but how one defines defect is often subjective. Parents might have certain expectations about gender, for example, and consider anything else as defective. In some Third World countries where "women have far fewer rights and female children are viewed as liabilities with bleak futures",
genetic testing Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression, or ...
is widely used for sex selection, and some couples have terminated otherwise healthy pregnancies because the child was not the desired gender. Research into the gene for homosexuality could lead to prenatal tests that predict it, which could be particularly problematic in countries where homosexuals are considered defective and have no legal protection. Such intervention is problematic morally, and has been characterized as "playing God". The general view of genetic engineering by Christian ethicists is stated by theologian John Feinburg. He reasons that since diseases are the result of sin coming into the world, and because Christian ethics asserts that Jesus himself began the process of conquering sin and evil through his healings and resurrection, "if there is a condition in a human being (whether physical or psychological) nderstood as disease and if there is something that genetic technology could do to address that problem, then use of this technology would be acceptable. In effect, we would be using this technology to fight sin and its consequences".


Abortion

Stanley Rudman boils down the abortion debate by saying that "if one says that the central issue between conservatives and liberals in the abortion question is whether the fetus is a person, it is clear that the dispute may be either about what properties a thing must have in order to be a person, in order to have the right to life – a moral question – or about whether a fetus at a given stage of development... possesses the properties in question" – a biological question. Most philosophers have picked out the capacity for rationality, autonomy and self-awareness to describe
personhood Personhood is the status of being a person. Defining personhood is a controversial topic in philosophy and law and is closely tied with legal and political concepts of citizenship, equality, and liberty. According to law, only a legal person (ei ...
, but there are at least four possible definitions: in order to be a true person, a subject must have ''interests''; possess rationality; be capable of action; and/or have the capacity for self-consciousness. A fetus fails to possess at least one and possibly all of these, and so it can be argued that the fetus is not a true person. Rudman points out how this approach becomes a slippery slope, as the argument can then be used to justify infanticide, which is not only not generally supported, but is defined by society as a crime. "Without assuming the Christian moral framework" concerning the sanctity of life, "the grounds for not killing persons do not apply to newborn infants. Neither classical utilitarianism nor preferential utilitarianism ... offer good reasons why infanticide should necessarily be wrong". Moral philosopher
Peter Singer Peter Albert David Singer (born 6 July 1946) is an Australian moral philosopher who is Emeritus Ira W. DeCamp Professor of Bioethics at Princeton University. Singer's work specialises in applied ethics, approaching the subject from a secu ...
in ''Practical Ethics'' describes the Christian argument as "It is wrong to kill an innocent human being; a fetus is an innocent human being" therefore it is wrong to kill a fetus. Rudman asserts the Christian ethic is more than a simple syllogism, it is "a narrative that includes the child in God's family, takes into account the entire context surrounding its birth, including the other lives involved, and seeks harmony with God's redeeming activity through Christ. It includes confidence in God's ability to sustain and direct those who put their trust in him."


Alcohol and addiction

The Christian ethic concerning alcohol has fluctuated from one generation to the next. In the nineteenth century, the largest proportion of Christians in all denominations resolved to remain alcohol free. While it is true that some contemporary Christians, including Pentecostalism, Pentecostals, Baptists and Methodism, Methodists, continue to believe one ought to abstain from alcohol, the majority of contemporary Christians have determined that moderation is the better approach. Ethicist Christopher C. H. Cook asserts that the primary question for Christian ethics revolves around the fact that alcohol misuse is a "contemporary social problem of enormous economic significance, which exacts a high toll in human suffering". All persons must, directly and indirectly, determine their ethical response to alcohol's enormous popularity and widespread acceptance in the face of its social and medical harm. The Christian ethic takes seriously the power of addiction to "hold people captive, and the need for an experience of a gracious 'Higher Power' as the basis for finding freedom".


Physician-assisted suicide

Physician Daniel P. Sulmasy lists arguments against physician-assisted suicide (PAS): those advocating it might do so for selfish/monetary reasons rather than out of concern for the patient; that suicide devalues life; that limits on the practice erode over time and it can become over-used; that palliative care and modern therapeutics have become better at managing pain, so other options are often available; and that PAS can damage a physician's integrity and undermine the trust patients place in them to heal and not harm. In Christian ethics, responses to assisted suicide are rooted in belief in personal autonomy and love. This remains problematic as the arguments commonly used to defend PAS are concepts of justice and mercy that can be described as a minimalist understanding of the terms. A minimal concept of justice respects autonomy, protects individual rights, and attempts to guarantee that each individual has the right to act according to their own preferences, but humans are not fully independent or autonomous; humans live in community with others. This minimalist view does not recognize the significance of covenant relationships in the process of decision making. Empathy toward another's suffering tells us to do ''something'' but not ''what'' to do. Killing as an act of mercy is a minimalist understanding of mercy that is not sufficient to prevent unethical acts. Battin, Rhodes and Silvers conclude that the Christian ethic asserts "life and its flourishing are gifts of God, but they are not the ultimate good, and neither are suffering and death the ultimate evils. One need not use all of one's resources against them. One need only act with integrity in the face of them."


Persistent vegetative state

VanDrunen explains that modern technology has treatments that enable a persistent vegetative state (PVS) which has led to questions of euthanasia and the controversial distinction between ''killing'' and ''letting die.'' PVS patients are in a permanent state of unconsciousness due to the loss of higher brain function; the brain stem remains alive, so they breathe, but swallowing is a voluntary reflex, so they must receive artificial nutrition and hydration (ANH) to survive. These patients can be without other health problems and live for extended periods. Most ethicists conclude it is morally sound to decline ANH for such a patient, but some argue otherwise based on defining when death occurs.


Environmental ethics

The twenty-first century has seen an increased concern over human impacts on the environment, including global warming, pollution, soil erosion, deforestation, species extinction, overpopulation, and overconsumption. There appears to be a strong scientific consensus that industrialized civilization has emitted enough carbon dioxide into the atmosphere to create a greenhouse effect causing global warming, yet debate rages primarily over the economic effects of limiting development. Michael Northcott, professor of ethics, says both issues will have to be dealt with: the reorientation of modern society toward recognizing the biological limits of the planet will not occur without a related quest for justice and the common good. Wogaman argues that the "doctrine of creation creates a presumption in favor of environmental conservation". Francis Schaeffer, evangelical theologian, said: "We are called to treat nature personally." Northcott says the incarnation shows God loves material reality, not just spirit. Recent studies indicate American Christians have become polarized over these issues. "For liberal Christians, the call to be a better steward is urgent, unequivocal, of the highest priority, and not to be subject to negotiation or compromise. For conservative Christians, however, the commitment to stewardship has become increasingly hemmed in with certain reservations and qualifications... Today, the official position of Southern Baptists, and of other conservative Christians, is indistinguishable from that of secular conservatives in the climate change denial, climate denial movement".


Animal rights

The debate over the inhumane treatment of animals revolves around the issue of personhood and animal rights. In the Christian ethic, personhood is related to the nature of God, who is understood in terms of community and inter-relationship. Within this view, the nature of moral community is not limited to a community of equals: humans are not equal to God yet have community with him. On this basis, Rudman argues that animals should be included in the moral community without being required to be regarded as persons. He says that, based on convictions which include the future transformation and liberation of all creation, a Christian view is obligated to take animal welfare seriously. Therefore, he concludes that the Christian ethic sees an emphasis on animal welfare as a better approach than the use of concepts of personhood and divine rights for addressing inhumane treatment of animals. Northcott adds that the Christian ethic, with its concepts of redemption of all physical reality and its manifestation of responsible stewardship in community and relation to others, is "a vital corrective to modern individualism which devalues both human and non-human distinctiveness".


Criticism

Some philosophers have described Christian ethics as intolerant, immoral, repressive, and infantilizing. According to Ronald Preston, the first of those four objections carries, historically seen, the most weight. According to Wayne A. Leys, modern ethics (e.g. by
Immanuel Kant Immanuel Kant (born Emanuel Kant; 22 April 1724 – 12 February 1804) was a German Philosophy, philosopher and one of the central Age of Enlightenment, Enlightenment thinkers. Born in Königsberg, Kant's comprehensive and systematic works ...
) was born because modern philosophers rejected traditional morality. Kant wanted solid, rational foundations for morality, not the weak foundation of a religion going into a decline. And he did not like that Christianity kept adults under "self-imposed nonage". Kant did not completely say farewell to Christian ethics, that is why Friedrich Nietzsche called him "a theologian in disguise". E.g. Kant did not reject God, the human soul, or the duty to God. By declaring that God and the soul are incognoscible he really meant insulating them from rational criticism.
